Tidal shifts in microhabitat use by Gobius cobitis: an adaptation to its feeding strategy?

Abstract

During high-tide, the majority of Gobius cobitis exhibit a microhabitat shift, moving up to the mid-intertidal walls and cliffs, a typical blenniid habitat that is not used by this species during low-tide. Observations on feeding behaviour that showed that fish behave as an ambush predator, being capable of hunting fish of considerable size, combined with its movements to typical blenniid habitats, suggest that this species may have a predatory role as a fish predator on the rock intertidal.
